RISC OS character set

The Acorn RISC OS character set was used in the Acorn Archimedes series and subsequent computers from 1987 onwards. It is an extension of ISO/IEC 8859-1.

Code page layout (standard)

At 0x83 is a box with another box inside it on the top left-hand corner, meaning "resize window".[1] At 0x84 is a 'bubble-writing' X, meaning "close window".[1] At 0x87 is an unusual character that is a subscript 8 followed by a superscript 7.[1] It is not proposed for Unicode.[2] At 0x88, 0x89, 0x8A, and 0x8B are left, right, up, and down bubble arrows for window scrollbars.[1] The Homerton font does not have these characters. EFF, a third-party supplier of RISC OS outline fonts, has a different, but similar character set.

The following table shows the RISC OS character set. Each character is shown with a potential Unicode equivalent if available. Space and control characters are represented by the abbreviations for their names. Differences from ISO-8859-1 are shown with darker shading on top of their legend colours.
